Question 1: The National Assessment of Educational Progress (NAEP) is administered annually to 4th,

8th, and 12th graders in the United States. On the math assessment, a score above 275 is considered an

indication that a student has the skills to balance a checkbook. In a random sample of 500 young men

between the ages of 18 and 20, the mean NAEP math score is 272. Do we have evidence to support the

claim that young men nationwide have a mean score below 275?
